I think buildings should imitate ecological systems. Ecological systems in nature before we had human beings you know interfere with them exist in a state of stasis - they are self-supporting, self-sustaining.

I think green buildings are extremely important but it's only part of the equation. A lot of people think that if I put a green building everything is going to be fine, but actually it's not just the green buildings we need, but green businesses, green governments, green economics. We have to extend the greening of buildings to our business and our lifestyles - that is the most important thing to do next.

I'm eternally optimistic about the future. I believe that if we are committed towards it and if we continue to educate people and get the whole world community to implement green features and aspects in not just the built environment not just in their lifestyles but in their businesses in their industries then we're heading towards a green future.

Better use of space, improving the insulation, getting more daylight into the buildings, reducing the energy consumption of the air conditioning and heating systems, making sure that the internal air quality is good, that we have increased natural ventilation opportunities in the mid seasons. You know these are some of the things we can do.

The ecologist has a much more comprehensive and holistic view of the world. We're looking at the natural environment as well as the human built environment and the connectivity between the two - how do the natural environment and the human-built environment interact and interface with each other.
